Hi
For many repair operations, we need to build up work piece before coating. For this, probably one of the best application is twin wire arc spray. But questions are;
These are different disciplines and many parameters are critical probably.
Lets say we must build up a rod then carbide coat 300 micron. Totally 5 mm must be filled.
We have;
Sand blasting (SB)
Twin wire arc spray (TWAS)
Machining with lathe (M) (im writing this because in some cases lathe is not suggesting)
Grinding (G)
